Detection of a Distinct Erythropoietin (EPO) Profile After Isoelectric Focusing in Patients With Familial Erythrocytosis

Drug Testing and Analysis, EarlyView.
A basic EPO IEF profile was identified in patients with familial erythropoiesis linked to mutations in noncoding parts of EPO gene. Comparison of blood and urine EPO profiles from these patients differed from adult wild‐type EPO (WT) and from Eprex‐administered patients. Patients' EPO do not differ from WT EPO after analysis using SDS‐PAGE/SAR‐PAGE. It
